LOOM.

Specification of Letters Patent.

Patented Feb. 24, 1920.

Application filed.l November 22, 1919. Serial No. 340,056.

. which the following is aspecification.

This invention relates to looms and has for its primary object theprovision of an apparatus of this character which is designed primarilyfor use in vocational schools,

` hospitals or the like or by beginners receiving instruction in the artof weaving, the structure being especially designed so that it can bereadily handled by convalescents and conveniently transported from oneplace to another.

Another object of the invention is to provide a loom which will consistof a yarn beam and cloth beam, mounted upon a novel form of frame sothat both beams can be manipulated from la common working position, theframe also including a reciprocating reed mounted upon the frame toclean the cloth beam and yarn beam and provided with means whereby thereed can be quickly adjusted .to change the position of the warp threadswhen it is desired to produce a shed between the threads.

Another object of the invention is to provide a loom consisting of aframe having a cloth beam and yarn beam and a reciprocating reed betweensaid beams, the said reed mounted in a carrier frame which is adapted toactas a batten for driving the weft thread against the previously wovenpart of e texture with a uniform sharp blow an thereby produce a threadsurface `having an even texture throughout.

With the above and other objects in view which will appear as the natureof the invention is better understood, the same consists in the improvedconstruction and novel arrangements of parts which will hereinafter befully described and particularly pointed out in the claims.

`In the accompanying drawings, has been illustrated, a single andpreferred form of the invention, it being, however, understood that nolimitations are necessarily made to .the precise structural detailstherein exhibited, but that changes, alterations and modificationswithin the scope of the claims may be resorted to when desired.

.ards 6 and 6 at one end an In the drawings t- Figure 1, is aperspective view of the loom,

` Fig. 2 is a plan view thereof.

In carryin use is made o? cludes parallel side bars 5--5, arallelvstandsimilar parallel standards 7`and 7 at the other end of the frame.Each set of said standards is connected at the base of the frame by abrace bar 8. The brace bars 8 and said parallel side bars 5-5 arearranged slightly above the lower ends of the standards 6 and 6', 7 andI7, so as to provide a clearance space below the side bars and permit theframe to be uniformly secured to a working table or the like. At the endof the frame which receives the yarn beam the bar 8 may be secured tothe table by a suitable clamp (not shown), whereby the frame may bepermanently held in a working position.

The cloth beam 9 has a trunnion 10 at one end which is freely journaledin thestandard 6, At the other end of the beam is a trunnion 11 ofcircular formation, the same journaled in a bearing'v passage 12 in saidstandard 6 so that the cloth beam can be revolved. The said standard 6is split on a vertical line 13 so that a slot 14 1s produced whichenters the bearing opening 12. This provides clampin extensions 15-15which may be brought 1n clamping engagement against the trunnion 11 bymeansof a fastening -bolt 16 which passes through said extensions 15-15at a point abovethe trunnion 11. From this construction it will be seenthat the cloth beam can be tensioned to any desired extent and held in arelatively fixed position.

The yarn beam 17 has its trunnions 18 mounted in bearing passages in thestandards 7 and 7. Beyond one of the standards, the beam is providedwith-a collar 19 having an annular series of passa es 20 in which akeeper in or latch 21 is a apted to engage so as to hold the beamagainst rotation when tension is placed on the thread. Each of the beamsis provided at its ends with lsuitable actuating handles 21.

Guide rods 22-22 extend longitudinally of the frame and are respectivelyconnected the invention into practice, a supporting frame which inwiththe standards 6 and 7 and 64 and 7 l frame. A relatively heavy frame 23is between the parts so as to permit said frame 23 to slide. without anyfrictional contact between the parts. The side bars 24 and 25 areprovided with brackets 28 which are apertured at 29 for the reception ofthe rods 22. This supports the frame 23 from the main frame and providesmeans whereby said fra-me 23 can be uniformly moved in a horizontalplane between the cloth beam and said yarn beam. The inner faces of theside bars 24 and 25 are grooved at 30. The undeil l face of the top `bar27 is grooved at 31. Slidable in the grooves y3()l is a reed 32, theupper end of which is adapted to be accommodated in the groove 27 on oneadjustment of th'e reed so that a large shed will be produced betweenthe upper and lower sets of the warp threads. The opening defined by thebars 24 and 25 and 26 and 27 is propor.

tioned so that suicient space isl provided beneath thereed to permit ofthe formation between the warp of a large shed when the reed is moveddownward.v If desired, the movement in a downward direction may beincreased by forming the lower bar 26 with a reed receiving groove 33similar to the groove 31 in the top bar 27.

The shed between the warp threads is produced by an actuator whichconsists of a cord or iexible connection 34, one terminal of which isconnected with the upper end of the reed and freely passed through aguide aperture 34 in the top bar 27. The

Icord is then guided through an eyelet 36.

on the b ar 25 and its free terminal is provided with a knob 37 whichmay -be engaged under 'a stop lug 38-when it is desired to hold thereedat the limit of its upward movement to produce a shed between thewarp threads.

From the construction described, it will be seen that the means 19, 20and 21, for holding the yarn beam against movement, and vthe means 16for holding the cloth beam are A.on the same side ofthe loom with thereed actuator, and that all of the `parts are therefore in convenientreach of the operator so that they can be individually' controlled asthe occasion necessitates. The

weight of the frame 24 acts as a batten whenthe reed is moved in thedirection of the cloth beam so thatfa sharp blow may be set up againstthe weft thread, driving the. l

same .against the previously woven' part of the texture so as to producean even surface throughout.

What is claimed as new is 1. Al loom Comprising a main frame, a yarnbeam, a cloth beam, means co-acting with each beam to hold'the sameagainst rotation, guidel rods carrled by the-main frame', a heddle frameslidable on the rodsbetween said beams, a heddle carried by said heddleframe, and means for adjusting the heddle in the frame to produce a shedbetween the warp threads.

2. A' loom comprising a main frame, a yarn beam, a cloth beam, means3o-acting with each beam to hold the same against rotation, guide rodscarried by the main frame, a heddle frame slidable on the rods betweensaid beams, a heddle carried by said heddle frame, means for adjustingthe heddle in the frame to produce a shed between the warp threads, saidadjusting means comprising -a retaining device carried by the heddleframe, a flexible connector carried by the heddle, and means on saidconnection to 'engage with the retaining device to hold the heddle inits adjusted position.

In testimony whereof Iy have aHiXed my signature.
